Button does not appear in an Active and appears in another

Question

I have a problem I don’t know where it is. I have a layout that runs a video, with a button in the front, only that the button does not appear although when I click on the area of the button it works normally.

The button should appear in the area in red.

Only I have another identical rotated layout, where the button appears, and the two have the same code.

It appears in the red area normally, and also works.

This is the layout where the button does not appear

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:rotation="180"
android:layout_width="match_parent"
android:layout_height="match_parent">

<VideoView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:rotation="180"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="true"
    android:id="@+id/vb_view"/>

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ImageButton
            android:id="@+id/vb_lutadores"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/lutadores"
            android:layout_alignParentBottom="true"
            android:layout_marginBottom="50dp"
            android:layout_centerHorizontal="true"/>

    </RelativeLayout>

</FrameLayout>

And that’s his code

package br.com.mscp.multiboxe;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.ImageButton;
import android.widget.VideoView;

public class Vb extends Activity {

    ImageButton vb_lutadores;

    VideoView vb_view;
    Uri vb_video;

    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.vb_layout);

        vb_lutadores = (ImageButton) findViewById(R.id.vb_lutadores);
        vb_lutadores.setEnabled(false);

        vb_view = (VideoView)findViewById(R.id.vb_view);
        vb_video = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.vb);
        vb_view.setVideoURI(vb_video);
        vb_view.start();

        vb_lutadores.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(Vb.this, Menu_lutadores.class));
                finish();
            }
        });

        Handler handler = new Handler();
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                vb_lutadores.setEnabled(true);
                vb_lutadores.bringToFront();
            }
        };

        handler.postDelayed(runnable, 800);
    } 
}

This is the layout where the button appears

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<VideoView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="true"
    android:id="@+id/vc_view"/>

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<ImageButton
    android:id="@+id/vc_lutadores"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/lutadores"
    android:layout_alignParentBottom="true"
    android:layout_marginBottom="50dp"
    android:layout_centerHorizontal="true"/>

</RelativeLayout>

</FrameLayout>

And that’s the code

package br.com.mscp.multiboxe;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.ImageButton;
import android.widget.VideoView;

public class Vc extends Activity {

    ImageButton vc_lutadores;

    VideoView vc_view;
    Uri vc_video;

    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.vc_layout);

        vc_lutadores = (ImageButton) findViewById(R.id.vc_lutadores);
        vc_lutadores.setVisibility(vc_lutadores.INVISIBLE);
        vc_lutadores.setEnabled(false);

        vc_view = (VideoView)findViewById(R.id.vc_view);
        vc_video = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.vc);
        vc_view.setVideoURI(vc_video);
        vc_view.start();

        vc_lutadores.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(Vc.this, Menu_lutadores.class));
                finish();
            }
        });

        Handler handler = new Handler();
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                vc_lutadores.setVisibility(vc_lutadores.VISIBLE);
                vc_lutadores.setEnabled(true);
                vc_lutadores.bringToFront();
            }
        };

        handler.postDelayed(runnable, 800);
    } ´
}

Someone knows where the mistake is because I can’t find it, if you can help I appreciate it

Answer 1

If I understood correctly, the desired result would be the button appear on top (on top) videoview.

Try to encompass both the Videoview and the button inside the FrameLayout

Framelayout is designed to lock an area on the screen to display a single item. [...] You can, however, , add several children a Framelayout. [...] Daughter views are drawn on a stack, with daughter added more recently at the top.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:rotation="180"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <VideoView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:rotation="180"
            android:layout_gravity="center"
            android:id="@+id/vb_view"/>

        <ImageButton
            android:id="@+id/vb_lutadores"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/lutadores"
            android:layout_gravity="center_horizontal|bottom"
            android:layout_marginBottom="50dp" />

    </FrameLayout>

</RelativeLayout>

Note that the RelativeLayout the third level has been removed and the properties in relation to it in the ImageButton and VideoView were replaced by android:layout_gravity as specified here
